Well I have it running, but don't know where to go from here. Like where do I configure the rooms. What's the syntax. How do I set up a mqtt broker and use it. Why is some if the "things" and "items" stock and I can't remove it. What's wrong with the weather plugin. Etc.

Like lots of (very basic) questions

Oh and most importantly how do I back up and move the configuration from my main computer to the intended server once that's needed?

you need to create new items under the items tab...if you want control of an entire room, create the item and make it a group item, them can include other items in that room when you make them as that group. once you have bindings installed, under things you will have the channels associated with each thing. you can then link that channel item to an item. you will then be able to contol them dirextly though the control tab.

sitemaps need to be made manually (text), but they are quite easy. id suggest installing the demo package and looking at the code in notepad++ (download it). make sure the extension you save it in is .sitemap. you will then be able to access it via a browser at http://(ip adress of your server openhab is running on):8080 choose basic or classic.

mqtt i havent tackled yet, but there IS A LOT of people here who can help. also, look in the tutorial section on here.

Hi, What is the recommended way to backup and restore an openhab2 installation? My usecase is that I would like to save and restore everything for an upgrade.
The easy stuff is (om my ubuntu sever): - conf folder - runtime/karaf/etc/openHAB-wrapper.conf for saving custom java options - runtime/karaf/bin/openHAB-service mostly for the "RUN_AS_USER" value - userdata/persistence - userdata/myopenhab/secret and userdata/uuid
What about configurations created by the paper ui? For example the hue …

if you run on a raspberry pi, @ThomDietrich will, when he can, add an option to do this in his config options.

i use rpi, but essentially you copy the user folder and some of the conf files. then replace them after you upgrade.

Basically everything under /etc/openhab2 (if you are using a Linux apt setup). Check the subchapters of http://docs.openhab.org/configuration/index.html - I know that a good chunk of info is missing in this area but you'll still learn a lot there.

From what I understand, they are in a readable JSON file, but it is completely possible, as I am doing myself now, to create the items in the paper ui, then link them to the channels. Then all you have to do is create the sitemap via text file. I'm sure someone will chime in if I am incorrect, or have more info to help.

My problem comes as (a lot of) the bindings I'm interested in are not or only partly (Or so it seems) configurable from paperUI. But configuring some in paperUI and afterwards being able to look in the text file to learn from that would be very nice.
